Another smallsat rocket company enters the market
Capitalism in space: A new Australian smallsat rocket company, Gilmour Space Technologies, has successfully test fired a new hybrid rocket engine.
This orbital-class rocket engine, developed by Australia and Singapore-based Gilmour Space Technologies (www.gspacetech.com), has successfully achieved 70,000 newtons (70 kilonewtons or 15,700 pounds-force) of thrust in what could be the world’s largest successful test fire of a single-port hybrid rocket engine. “These results prove that we have the core technology needed to enable low-cost small satellite launches to space,” said its CEO & Founder, Adam Gilmour. The company’s mission: to carry payloads weighing up to 400 kg to low earth orbit (LEO) from 2020.
Unlike the vast majority of commercial rockets today, which use either solid- or liquid-fuelled engines, Gilmour Space is pioneering new hybrid-engine rockets that combine a liquid oxidiser with a proprietary multi-material 3D printed solid fuel. Indeed, the Queensland-based company first made headlines in 2016 when it successfully test launched a subscale rocket to an altitude of 5km using its 3D printed rocket fuel.
The static fire test, which can be seen in a video at the link, was very short, less than 10 seconds. Since one of the big problems of hybrid engines has been to get them to fire smoothly and precisely for long periods of time, I remain skeptical. They might have some good engineering here, but I don’t yet see the makings of a rocket.

Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

Does the 3-d printing introduce the key to solving the smoothness in firing problem previously seen in Hybrid engines?
